Question 1129077
<br>
Unclear for at least a couple of reasons....<br>
Is "log19 ..." log, base 19, of ...? or is it log(base 10) of 19?<br>
"to base 10" is BAD language.  "to" is used to indicate powers (exponents), not logarithms.<br>
...or perhaps "to base 10" corresponds to the phrase in the statement of the problem "using the indicated base".<br>
I would guess that the intended problem is to express log, base 19, of 53.875 as a ratio of logs base 10.  But I'm not going to spend any time working that problem if I don't know it's the right one.
